4 point system. Quad set up How does it work?

Can someone point in the right direction to info on setting up a 4 point system. Not sure the proper name for it. I have been approached by someone who wants a surround sound system of F121s & res 4s. (stereo stack at the front, and two stacks behind at the back.) he is wanting to keep the sound contained as it is in a small town

Look at having the the opposing bins out of phase with with each other. To keep it contained better look at having some thing like bales of hay behind each stack.

Don’t do this. The phase thing. Hay bales is good. Heston barrier better.

If you want do four point or four corner - not the same, in my eyes - then experiment. There are no rules and it depends on the system, the room, the content. None of the good four corner rigs - and there are literally a handful - were anywhere close to right first time. Also it isn’t ‘surround sound’ unless the content is delivered that way.

Likewise, if you four point the bass, you’re not necessarily going to have less noise off site. It can be way more. As ever, it depends on the boxes, the spacing, and the location. Oh, and the weather.

My main guidance is don’t be afraid to turn thing down, or even off, or high pass them more than you would think. Or low pass.

Heston bale is a size of hay or straw bale, price of which should drop rapidly as soon as there is a week or two of dry weather.

Thank you for you replies.

That all depends on the system and the design and implementation. If you’re ground stacking then you’re up against the huge disparity in forward aspect ratio and level and tonality front to back.

It can help reduce spill outside the arena but you’re going to have to run the entire rig quieter to compensate for the additional summation ( and destruction)

More boxes does not equal better or even louder. We have a client who insists on a rear stack setup despite me simulating and measuring a reduction in on site level in the dance floor and more noise offsite. Client is paying though...
